Brakes are sticking on even when cold. Can sometimes be releases by pumping pedal. have recently acquired car and assume this is probably degraded brake fluid. No hand book or Adrians book as yet so any advice welcome!

Nice looking car! (funny mirrors though )

Could be lifting baseplates on the calipers - common problem. It's worth doing a search on this forum for calipers.

Cheers

Steve, since you are new, you may not know that brakes are very, very easy to work on. Changing pads and bleeding the fluid can be done by almost anyone. Go to p-car.com and look at the DIY section for great directions on brakes. The site is 993 biased but the brakes on the 964 require the same procedure.

Had a look - very useful site. Do you have a view on disconnecting battery when in store (couple of weeks at a time) or fitting a triclke charger - someone has said if disconnected the engine management goes down?
many thanks

You don't disconnect the battery on a trickle charger, you leave it connected and the trickle charger ensures the battery stays charged.

My 964 sits for a week or two at a time between starts and use. I only have had one problem where the battery died and I needed to jump it (and then charge it by driving around). If you have a problem, get a trickle charger. Don't spend the money if you don't have a problem (is my view).

I'm much more familiar with 993's - on a 993 if you disconnect the battery, the ECU must re-learn some settings. This takes about 20 minutes while driving. After 3 cold starts, everything is "learned". This does not mean that the car does work well as the ECU is relearning, you may just not get optimium performance (which doesn't really matter in street driving anyway).

Thanks again - very helpful

In regards to the battery-Porsche also makes a charger that connects through the cigarrette lighter on the dash. I am using one this winter and am VERY impressed. A little overpriced but allows the door to be closed and it's chip keeps the battery fully charged. I was skeptical-always used a trickle charger before-but am a convert now.
